Hey @anttiviljami
Firstly thanks for reporting.

I experience the same in my MacBook air Safari. None of the navbar items can be rendered:

In Chrome it works fine.

I'm on Catalina (...yes still).

@benjagm still happening for me

[Relequestual]

It looks like lookbehind support was added in Safari 16.4. I assume this means iOS 16.4 onwards too.
Relevant PR: WebKit/WebKit#7109

If are are able to update, this would be ideal.
If anyone else is able to identify and fix the problem, we would welcome a further PR.

This is a difficult one @MonalSD . All yours.

I tried myself in this draft PR but it didn't work: #257

@benjagm I tried but couldn't reach to the desired solution. Thankyou

[benjagm]

Thanks Monal! This is a really difficult bug. I also spent some days working on it too so .... thanks for trying!
